Abstract: 1,020,449. Visual and audible signalling. C. A. PARSONS & CO. Ltd. May 13, 1963 [June 22, 1962], No. 24064/62. Heading G4F. [Also in Division H3] An alarm communicator comprises a first circuit having a first semi-conductor four-layer device SCR1 connected to a first pulsed D.C. supply A; a second circuit having a second semi-conductor four-layer device SCR2 connected to a second, complementary, pulsed D.C. supply B; means IC, for triggering the first device SCR1 in response to a fault condition; means AC for triggering the second device SCR2 in response to the acknowledgment of a fault; means (diode D4, resistor R4) connecting the device SCR1 to device SCR2 to provide a maintaining current for SCR2 through SCR1; means for maintaining the first device, SCR1, conductive; and a warning circuit connected to both the first and second circuits. In a first embodiment, Fig. 1, closure of alarm contacts IC connect the trigger electrode of a silicon controlled rectifier SCR1 to a positive potential to switch it on. The rectifier is then maintained conductive by the D.C. supply through R2 even if the fault clears, and the pulsed supply on line A causes alarm lamp L to flash. To acknorledge the alarm, an operator closes contacts AC to fire silicon controlled rectifier SCR2 which is then held conductive by the current through SCR1, diode D4 and resistor R4. Line B then supplies a second pulsed supply to lamp L in antiphase with the first so that the lamp is lit steadily. Further visible and/or audible alarms may be connected to point T. The circuit may be modified to respond to persistent fault conditions only by removal of link P1 so that rectifier SCR1 will only be held conductive as long as the fault condition persists. In an alternative circuit, Fig. 2 (not shown) the SCR's are replaced by PNPN diodes and the triggering circuits are modified to cause the negative potential on the cathodes of the diodes to be increased.

Title: Improvements relating to the production of rabis vaccine
IPC: A61K39/205
Filed: 1954-08-19
Abstract: In the production of a rabies vaccine, virulent rabies virus is attenuated by introducing it into the yolk sac or allantoic sac of an egg incubated for 5-9 days, and allowing to grow for 5-12 days; the virus particles are then removed, introduced into another incubating egg, and the procedure repeated until at least 150 passages through incubating eggs have taken place and the virus has lost its pathogenicity.  The senal passages may be interrupted by passage through other hosts, e.g. day old chicks or baby mice.  For the preparation of the vaccine, the living embryos are triturated and filtered, streptomycin or penicillin is added if desired, and the suspension is held at 4 DEG C. for two hours, then filtered, frozen and dried; if no antibiotics are added, the suspension may be filtered immediately.

Filed: 1961-07-06
Abstract: 972,016. Separating normal and other hydrocarbons. ESSO RESEARCH & ENGINEERING CO. July 6, 1961, No. 24464/61. Heading B1L. The separation of n-paraffins and n-olefines from a mixture of hydrocarbons is carried out continuously by introducing the gases into a fluidized bed of molecular sieve zeolite particles at 100-500 ‹F. which adsorb the n-hydrocarbons, continuously passing the particles with adsorbed hydrocarbons to a fluidized zone at 200-600 ‹F. into which is passed a stripping gas consisting of n-olefines or comprising nparaffins having one or two carbon atoms more or less than said adsorbed hydrocarbons, and recycling the particles now containing adsorbed n-hydrocarbons from the stripping zone, to the adsorption zone: the required n-hydrocarbons are withdrawn from the stripping zone and the remaining hydrocarbons in the initial gas mixture together with n-hydrocarbons from the stripping gas are withdrawn from the adsorption zone. The hydrocarbon mixture is passed into vessel 1 (see Figure) through preheatervaporizer 2 containing the adsorption bed. The n-paraffins in the mixture are selectively adsorbed in the bed, whilst the unadsorbed fraction passes out through line 6 into the separator 13. A constant bleed of zeolite is withdrawn at 7, entrained in the stripping gas and conveyed to vessel 12 containing the stripping bed. Desorption of the n-paraffins and replacement of same by olefins or other nparaffins from the stripping gas occurs and the desorbed n-paraffins pass out through line 18 to the separator 20 where they are separated from the residual stripping gas. A continuous bleed of zeolites, containing adsorbed stripping gas passes from 12 by line 15 into a gaseous stream of the incoming hydrocarbon mixture flowing along line 28, and thence into vessel 1 via line 26. Desorption of the stripping gas occurs, with replacement of same by n-paraffins present in the hydrocarbon mixture, when the zeolite enters the fluidized bed, and the released olefines pass out of vessel 1 with the unadsorbed fraction of the hydrocarbon mixture. Separation of the olefines from this mixture is effected in separator 13. 1-10% of zeolite is continuously withdrawn for regeneration at not more than 850 ‹F. in a fluidized bed in vessel 30, using flue gas, air, or other gas that will desorb the polar contaminants and then returning the regenerated zeolite to vessel 12. Specified hydrocarbons which may be separated are n-hexane and n-heptane from light virgin naphtha containing isomeric hexanes and heptanes cycloparaffins and aromatics using propylene or butylene, e.g. as cracked refinery gases, as stripping gas; propylene from cracked gas using C 6 -C 7  n-paraffins ; n-butylene from cracked gas using C 8 -C 9  n-paraffins ; ethylene using C 3 -C 5  n-paraffins; C 6 -C 7  n-paraffins from C 6 -C 7  iso- and cyclic paraffins both contained in a light narrow cut virgin naphtha feed using a heavier narrow cut virgin naphtha desorbent containing n C 8 -C 9  paraffins.

Abstract: 1301789 Borehole logging CHEVRON RESEARCH CO 19 April 1971 [25 March 1970] 24768/71 Heading G1N The presence and location of a horizontally disposed, electrically resistive geological anomaly e.g. 1 in an earth formation adjacent to a well bore, 27 when the anomaly lies in the vicinity of a massive vertically disposed electrically resistive geological anomaly 25 is determined using a "split array" electrode array. The well bore is traversed by the "split array" which comprises vertically disposed current source electrode A, 20 and current collector electrodes M21 and N22 and a distant sink electrode 32. Current source electrode A is energized to pass current into the earth formations adjacent the well bore and the difference of potential ## between electrodes M, N measured. The apparent resistivity # #  of the formations between electrodes MN is then determined from # #  = 4###/IG where I is the current emitted by the source electrode A and G is the tool geometry factor <SP>1</SP>/AM-<SP>1</SP>/AN where AM, AN are distances of the collector electrodes from the source electrode. The output from differential analogue computer 42, is displayed as a trace 45 on record 50 and is a measure of the resistivity effects of horizontal anomalies. This trace is compared with a depth correlated trace 49 representing apparent resistivity derived from measurements obtained by apparatus other than "split arrays" and which may be theoretically calculated. Detection of oil sand 2, 4, 6, 8, 10, 12, 14 and irregularities 1 is accomplished by noting the differences in the traces and the magnitude of the difference is employed to indicate the location of the horizontal anomalies. Since massive vertical anomalies have no differential effect on the current collector electrodes the output at 42 is independant of such anomalies. Electrodes M, N are preferably arranged at equal distances from the electrode A.
